CAUTION: Stresses above those listed in âAbsolute Maximum Ratingsâ may cause permanent damage to the device. This is a stress only rating and operation
of the device at these or any other conditions above those indicated in the operational sections of this speciï¬cation is not implied.
NOTES:
1. The ICM7216 may be triggered into a destructive latchup mode if either input signals are applied before the power supply is applied or if
input or outputs are forced to voltages exceeding VDD to VSS by more than 0.3V.
2. θJA is measured with the component mounted on an evaluation PC board in free air.
Electrical Speciï¬cations VDD = 5.0V, VSS = 0V, TA = 25oC, Unless Otherwise Speciï¬ed
